Two Different Legal Systems for Workplace Injuries
If you were injured at work in Massachusetts, you may be wondering whether to file a workers’ compensation claim, a personal injury lawsuit, or both. The answer depends on the specific circumstances of your accident. Understanding the difference between these two legal systems is essential to protecting your rights and maximizing your recovery.

Workers’ Compensation: The Default System for Work Injuries
Massachusetts workers’ compensation, governed by MGL Chapter 152, is a no-fault insurance system that provides benefits to employees injured on the job regardless of who caused the accident. You do not need to prove your employer was negligent — only that you were injured in the course of your employment.
Workers’ comp benefits in Massachusetts include: payment of all reasonable and necessary medical expenses related to your work injury (no cap); temporary total incapacity benefits equal to 60% of your average weekly wage while you cannot work; temporary partial incapacity benefits when you return to work at reduced capacity; and permanent total incapacity benefits for injuries that permanently prevent any work.
The tradeoff: workers’ compensation is generally your exclusive remedy against your employer. In most situations, you cannot sue your employer in civil court for a work injury, even if their negligence caused it. However, this limitation applies only to your employer — it does not prevent you from suing third parties who contributed to your injury.
Personal Injury Claims: When Can You Sue?
A personal injury lawsuit allows you to recover the full range of damages — including pain and suffering — that workers’ comp does not cover. You can bring a personal injury claim against any party other than your employer whose negligence contributed to your work injury. Common third-party defendants in Massachusetts work injury cases include:
Equipment and product manufacturers: If defective machinery, tools, or safety equipment contributed to your injury, the manufacturer may be liable under product liability law.
Property owners and general contractors: On construction sites, if the general contractor or property owner failed to maintain safe conditions, they may be liable to subcontractor employees injured on-site.
Negligent drivers: If you were injured in a vehicle accident while working — driving a company vehicle, making deliveries, or traveling between job sites — you may have a workers’ comp claim for your employer’s coverage and a personal injury claim against the at-fault driver.
Staffing agencies: If you were placed through a staffing agency and injured at a client’s facility, questions of liability between the agency and the client can give rise to third-party claims.
Key Differences Between Workers’ Comp and Personal Injury
Fault: Workers’ comp requires no proof of fault. Personal injury requires proving someone else was negligent.
Damages: Workers’ comp covers only medical expenses and a portion of wage loss. Personal injury allows full recovery including pain and suffering.
Process: Workers’ comp goes through the Department of Industrial Accidents (DIA). Personal injury cases go through the Massachusetts court system.
Employer liability: Workers’ comp prevents most lawsuits against your employer. Personal injury targets third parties.
Coordinating Workers’ Comp and Personal Injury Claims
The good news is that these claims are not mutually exclusive. You can collect workers’ compensation benefits and pursue a third-party personal injury claim simultaneously. However, Massachusetts law requires you to reimburse your workers’ comp insurer out of any third-party settlement or judgment — this is called a workers’ comp lien. Your attorney manages this process to ensure the lien is properly addressed and you retain the maximum net recovery.
